Morphology

halo + blight

The compound is directly descriptive: 'blight' names a plant disease and 'halo' describes the ring-like symptom, so a learner who knows both words can infer it is a disease producing halo-like spots on leaves. This noun+noun composition is compositional and mirrors descriptive patterns in many languages, making the meaning transparent to B1 learners who know the constituents.

Etymology

Halo blight comes from how the sick leaves look: dark spots often with a pale yellow ring or halo around them, and the word blight means a plant 'disease' that damages leaves. So the name describes a 'disease' that makes spots with a yellow ring on leaves.
